Research interests:

My present research activities focus on the vertical flux of organic biomass and sinking particles (> 50 μm) in high latitude regions (Barents Sea; Adventfjorden, Svalbard) and potential drivers of major sedimentation events such a turbulence, upward nitrate flux, phytoplankton and zooplankton composition, or glacial run-off. This meets my research interests of field-based research with a major focus on physical-biological interactions.
